Johnson Controls VMA1400 Variable Air Volume Modular Assembly

Variable Air Volume Modular Assembly

The Variable Air Volume Modular Assembly (VMA) is a family of configurable digital controllers. Differing models in the VMA1400 series combine a controller, pressure sensor and/or actuator housed in one pre-assembled unit. The VMA1400 series is available in four models:
• Cooling Only (VMA1410)
• Cooling with Reheat and/or Fan (VMA1420)
• External Actuator (VMA1430)
• Metasys Zoning Package (VMA1440)

The VMA1410, VMA1420, and VMA1440 use an integrated actuator with a stepper motor drive for quick and accurate damper positioning. The VMA1410, 1420, 1430 are designed for pressure-independent, single duct systems. The VMA1420 and VMA1430 can also be used with parallel or series fan-powered boxes, supply/exhaust applications, and dual duct systems. The VMA1440 is used exclusively as part of the Metasys Zoning Package. See the Metasys Zoning Package Product Bulletin (LIT-639050) for details.

• easy-to-handle unit with a compact footprint
• pre-wired controller with pressure sensor and actuator for reduced installation time (VMA1430 uses external actuator, VMA1440 has no pressure sensor)
• fast response actuator that drives the damper from full open to full closed (90°) in 30 seconds (VMA1410, VMA1420, VMA1440) for reduced commissioning time
• continuous loop tuning through proportional adaptive algorithms using patented P-Adaptive and Pattern Recognition Adaptive Control (PRAC) technologies
• advanced diagnostics that identify and correct system deviations related to flow, damper travel, and energy
• N2 network communications for integrating VMA as a part of a facility management system with an NCM or N30 Series Supervisory Controller
• simple question/answer software format for quick, easy configuration of project-specific applications. The VMA1400 Balancing Tool (VBT) software can be used with handheld interfaces (such as 3Com® PalmPilot™) to easily read and adjust parameters (not available for VMA1440). VBT software is included in M-Tools or can be ordered separately.
